Description

Technical Field

[0001] This utility model relates to the field of cleaning robot technology, and in particular to a mobile device for a wall cleaning robot. Background Technology

[0002] With the acceleration of urbanization, high-rise buildings are becoming more and more common, and the demand for cleaning building exteriors is increasing. Traditional cleaning methods rely on manual high-altitude operations, which are not only inefficient but also pose significant safety hazards. Therefore, a cleaning robot is needed to carry out cleaning work. Various types of wall cleaning robots have gradually entered the market. These robots achieve wall crawling and cleaning functions through different walking mechanisms, providing the necessary action basis for the smooth progress of cleaning work.

[0003] A search revealed Chinese Patent Publication No. CN215016682U, which discloses a glass cleaning robot belonging to the field of cleaning robots. Based on a negative pressure adsorption method using a fan, the glass cleaning robot includes a negative pressure adsorption device, a walking mechanism, a frame, and a glass cleaning device. This invention uses the negative pressure adsorption device to adsorb the entire cleaning robot onto a glass window or glass wall. During movement, the walking mechanism automatically cleans the glass surface using the glass cleaning device. This invention effectively replaces the high-risk manual work of cleaning windows and glass walls at heights while achieving efficient mobile cleaning, reducing the workload and danger of the work. However, the aforementioned structure does not consider stability during movement, lacks the necessary adsorption pressure, and has poor adaptability, making it difficult to adapt to different wall surfaces to meet work requirements.

[0047] Working principle: By controlling the movement of the dual-output shaft motor 3 inside the housing 1, the transmission shaft 4 at its output end is rotated, which in turn drives the transmission wheel 5 connected to the transmission shaft 4 to rotate, thereby driving the belt 6 installed on the transmission wheel 5 to move the device. Since multiple suction cups 7 are distributed on the belt 6, it can adhere to the wall surface and move. Furthermore, a servo motor 9 is installed at the bottom of the housing 1 through a connecting block 8. When moving, the servo motor 9 drives the roller brush 10 to rotate and clean the wall surface. This structure can increase the adhesion to the wall surface, clean the wall surface while moving, reduce personnel intervention, improve work quality and efficiency, reduce the danger of working at height, ensure the safety of the operation, and meet the cleaning needs.

[0048] When the robot starts, a vacuum pump 201 is installed at the bottom of the outer shell 1, and multiple pipes 202 are connected to the vacuum pump 201. Each pipe 202 is controlled by a control valve 203 and is connected to a suction cup 204. When the vacuum pump 201 operates, the opening and closing of the control valve 203 creates a negative pressure inside the suction cup 204, causing it to adhere tightly to the wall. A telescopic rod 206 is installed on the top of the suction cup 204 and is mounted on the bottom of the outer shell 1 via a mounting block 205. When the telescopic rod 206 is working, its posture can be adjusted, and the suction cup 7 is adsorbed by pressure. This structure improves the stability of the robot during operation, ensuring that the robot can maintain stable adhesion on walls of different materials and flatness, thus meeting the lifting requirements.
